3.4.3
Power Conditioner
The Power Conditioner mode is characterized by the UPS running in the double
conversion mode without a DC source connected. In the Power Conditioner
mode, the UPS provides conditioned output voltage and frequency. The UPS can
also support high nonlinear loads without ITHD on the input. The UPS meets the
qualifications outlined in this product specification, except for the conditions
below.
When in the Power Conditioner mode, the UPS has the following functionality
and limitations:
1.
The UPS runs in the double conversion mode and the battery alarms are
turned off.
2.
Because there is no DC source, loss of utility power results in the UPS losing
power and shutting down.
3.
The UPS sustains up to -50% input voltage tolerance, unless the current limit
is reached.
4.
If the rectifier is turned off, the UPS attempts a transfer to the bypass mode.
5.
The ESS mode is not available.
3.4.4
Frequency Converter
The Frequency Converter mode is characterized by the UPS running without the
bypass mode available. The output frequency can be configured to be different
from the standard input frequency (for example, 60 Hz output, 50 Hz input). The
UPS can also support high nonlinear loads without iTHD on the input. The UPS
meets the qualifications outlined in this product specification, except for the
conditions below.
When in the Frequency Converter mode, the UPS has the following functionality
and limitations:
1.
Operation is the same as when in the double conversion mode with no
bypass available.
2.
Bypass alarms are suppressed.
3.4.5
Sync Control
The Eaton® Sync Control maintains the critical load outputs of two separate
single UPS systems in synchronization. Use of the Eaton Fixed Master Sync
Control provides uninterrupted transfer of the load from one load bus to another
by means of downstream, dual-source, solid-state transfer switches. Without the
load sync option, the two system output (critical load) buses can become out of
phase with each other. This condition occurs when suitable bypass sources are
not available or when the bypass sources feeding each system are not in sync
with each other. Examples of this condition are two systems supplied by separate
generator sets, or situation where the bypass sources for the two systems are
lost.
